java.security.AccessControlException: доступ запрещен («java.util.PropertyPermission» «jna.boot.library.path» «читать»)

Question

У меня возникли некоторые проблемы при запуске моей подписью веб-апплет,

он прекрасно работает в Eclipse, но как только я загрузить на веб-страницу, я получаю этот журнал ошибок:

Я считаю, что это проблема с разрывом из песочницы, и связи с компьютером.

Может использоваться AccessController.doPrivileged решить проблему? Каковы мои параметры, кроме изменения файла политики?

Answer 1

Оказалось, проблема, с которой я столкнулся, заключалась в том, что мои ссылки на файлы Jar (за пределами основного банку) не были подписаны, и после их подписания проблема исчезла.
